Relationship Between Coefficient and Compressibility of Carbenium Ion Hydrolysis Rate

Abstract

A linear relationship between the rate constant of hydrolysis and a recently introduced parameter, group compressibility of a series of proposed carbenium ions (28 ions) are shown as log k_w = 17.00224– 4.28332Gβ′. According to these group compressibilities, a new substituent constants, σ_p (Gβ′), are also introduced, which correctly explains the experimental electrophilicity ordering established in terms of experimental scales.
